<P>PROBLEM TO BE SOLVED: To provide a rotating electric machine control device, a method and program for controlling the rotating electric machine, capable of compensating for a change of torque with eliminating causes other than demagnetization of permanent magnet during rotating electric machine control. <P>SOLUTION: This rotating electric machine control device 40 has roughly three signal processing flows. A first structural portion is a portion that generates a three-phase driving signal supplied from a torque command value 42 to an inverter circuit 20 and is equivalent to a portion from a d, q current map 44 to PWM conversion 54. A second structural portion is a portion that detects a driving current value 32 from a motor/generator 30 and feeds back to a current command, and performs coordinate conversion 56 for the driving current value 32 and is equivalent to a loop in which a current command value is input into a subtractor 48. A third structural portion is a portion that computes driving power and cycle of the motor/generator 30, obtains a torque estimation value and compensates for the current command value based on the torque estimation value, and compensating for a torque change and is equivalent to a power computation portion 58, a cycle computation portion 60, a torque estimation portion 62, and a current command compensation portion 70. <P>COPYRIGHT: (C)2008,JPO&INPIT |
